Frequently Asked Questions

Methotrexate roz kyun nahi lete?

Methotrexate is given WEEKLY for RA and psoriasis — daily dosing is a fatal medication error that can cause serious toxicity and death. Confirm the dose schedule in writing with your doctor.

Methotrexate ke sath folic acid kyun leni hoti hai?

Folic acid 5mg weekly (on a SEPARATE day from Methotrexate) is co-prescribed because Methotrexate blocks folate metabolism — folic acid reduces side effects (mouth ulcers, nausea).

Methotrexate ke sath kaunse tests zaroori hain?

CBC (Complete Blood Count), LFTs (Liver Function Tests), and creatinine should be monitored regularly. Always follow your doctor's monitoring schedule.

Kya Methotrexate ka dose khud se adjust kar sakte hain?

Absolutely not — only a rheumatologist or specialist adjusts the Methotrexate dose. Increasing or decreasing the dose on your own is dangerous.

Methotrexate kitni der mein kaam karna shuru karta hai?

The full DMARD effect of Methotrexate in RA becomes apparent after 6-12 weeks. Regular follow-up and monitoring are still required throughout.
